In medical billing, submitting a claim is more than just sending a bill to an insurance company. Every claim must contain accurate information, follow the correct billing format, and reflect the healthcare services provided. Even a small mistake can lead to a rejected claim, delayed reimbursement, or additional administrative work for your billing team.
If you work in healthcare administration, medical billing, or revenue cycle management, you have probably come across two important terms: institutional claims and professional claims.
But what is the difference between them? Why do hospitals typically submit institutional claims, while physicians and other practitioners often submit professional claims? And how can understanding these differences help your organization improve its billing process?
Let’s break it down in simple terms.
What Are Institutional Claims vs Professional Claims?
The primary difference between institutional claims and professional claims is the type of claim being submitted and the billing format used.
Institutional claims are generally used by hospitals and other eligible institutional healthcare providers to bill for facility-based services. These claims may include facility charges, room and board, nursing services, medical supplies, and other eligible institutional expenses.
Professional claims are generally used by physicians and other eligible healthcare practitioners to bill for professional services, such as consultations, examinations, evaluations, and medical procedures.
According to the Centers for Medicare & Medicaid Services (CMS), institutional claims use the 837I electronic format or CMS-1450 paper form, while professional claims use the 837P electronic format or CMS-1500 paper form.
The distinction matters because each format has its own reporting requirements, data fields, and billing rules.
What Is an Institutional Claim?
An institutional claim is a healthcare billing claim submitted by an eligible institutional provider for covered services delivered in a facility or institutional setting.
Hospitals are a common example, but institutional billing is not limited to hospitals. Depending on the provider type and applicable payer rules, institutional claims may also be used by skilled nursing facilities, home health agencies, hospices, and other eligible healthcare organizations.
These claims may include charges associated with the facility, services provided during a patient’s stay, and other billable items covered under the applicable reimbursement arrangement.
Which Form Is Used for Institutional Claims?
Institutional claims are commonly submitted using the following formats:
- 837I: The electronic institutional healthcare claim format.
- CMS-1450 (UB-04): The standard paper institutional claim form, when paper submission is permitted.
Most healthcare organizations submit claims electronically. Paper claim forms may be used when permitted by the payer and applicable requirements.
What Information Does an Institutional Claim Include?
Depending on the service, payer, and claim type, an institutional claim may contain:
- Patient identification and insurance information.
- Billing provider and facility details.
- Admission and discharge dates, when applicable.
- Dates of service.
- Revenue codes and associated charges.
- Diagnosis codes.
- Procedure codes and other applicable service codes.
- Type of bill and other institutional billing information.
- Discharge status, when required.
- Authorization and supporting information, where applicable.
Not every institutional claim requires every field. For example, an outpatient facility claim may not include admission and discharge information in the same way as an inpatient hospital claim.
The key is to follow the requirements that apply to the specific service and payer.
Example of an Institutional Claim
Imagine a patient is admitted to a hospital for treatment following a serious infection.
During the patient’s stay, the hospital provides a room, nursing care, laboratory services, medication administration, and other medically necessary facility services.
The hospital’s billing department reviews the services and applicable charges, verifies the required documentation, and submits an institutional claim to the patient’s insurance company.
The claim represents the hospital’s billable services and is processed according to the payer’s coverage and reimbursement rules.
If a physician also bills separately for professional services, that physician’s claim may be submitted separately as a professional claim.
What Is a Professional Claim?
A professional claim is used by physicians and other eligible healthcare practitioners to bill for professional healthcare services.
These services may include patient consultations, office visits, diagnostic interpretations, evaluations, procedures, and other services performed by qualified practitioners.
Professional claims are common in physician practices, specialty clinics, outpatient care, and other settings where practitioners bill for their professional services.
However, the place where a service is delivered does not automatically determine the claim type. For example, a physician working inside a hospital may still submit a professional claim for the physician’s services.
Which Form Is Used for Professional Claims?
Professional claims are commonly submitted using:
- 837P: The electronic professional healthcare claim format.
- CMS-1500: The standard paper professional claim form, when paper submission is permitted.
The CMS-1500 is used by eligible non-institutional providers and suppliers to bill Medicare and certain other payers under applicable requirements.
What Information Does a Professional Claim Include?
A professional claim may include:
- Patient demographic and insurance details.
- Billing and rendering provider information.
- National Provider Identifier (NPI), where required.
- Date of service.
- Place of service.
- Diagnosis codes.
- CPT or HCPCS procedure codes, as applicable.
- Modifiers, when appropriate.
- Units of service.
- Charges for professional services.
- Referring or ordering provider information, when required.
- Authorization details, where applicable.
The exact requirements depend on the service, payer, provider type, and applicable billing guidelines.
Professional billing teams must ensure that procedure codes, diagnosis codes, provider details, and other claim information accurately reflect the services documented in the medical record.
Example of a Professional Claim
Suppose a patient visits a cardiologist for an evaluation of recurring chest discomfort.
The cardiologist reviews the patient’s medical history, performs an examination, evaluates the symptoms, and documents the findings and treatment plan.
The physician’s billing team uses the documentation to identify the appropriate diagnosis and procedure codes, verify the required provider information, and submit a professional claim to the patient’s insurance company.
If the patient also receives hospital based testing, the facility may submit a separate institutional claim for its billable services, depending on the circumstances and applicable billing arrangements.
The professional claim represents the practitioner’s eligible services, while the institutional claim represents the facility’s eligible charges.
Institutional Claims vs Professional Claims: Key Differences
Although both claim types are used to request reimbursement from healthcare payers, they differ in several important ways.
| Comparison | Institutional Claims | Professional Claims |
|---|---|---|
| Primary purpose | Bills for eligible facility or institutional services | Bills for eligible professional healthcare services |
| Common billing entities | Hospitals, skilled nursing facilities, home health agencies, and other eligible institutions | Physicians, qualified practitioners, and other eligible suppliers |
| Electronic format | 837I | 837P |
| Paper claim form | CMS-1450 (UB-04) | CMS-1500 |
| Common billing information | Revenue codes, institutional billing details, facility charges, and applicable dates | CPT/HCPCS codes, provider details, modifiers, units, and professional charges |
| Examples | Hospital stays and eligible facility outpatient services | Office visits, professional evaluations, consultations, and procedures |
| Payment considerations | Facility payment methodologies and institutional reimbursement rules | Professional fee schedules and practitioner reimbursement rules |
| Common challenges | Incorrect revenue codes, type-of-bill errors, and incomplete facility information | Incorrect procedure codes, modifier errors, and missing provider information |
These are general distinctions, not universal rules for every payer or service. Actual claim requirements and payment methods vary by payer contract, provider enrollment, service type, and applicable regulations.
Can a Hospital Submit Both Institutional and Professional Claims?
Yes. A hospital or another eligible institutional organization may submit institutional claims for facility services and professional claims for separately billable professional services when the applicable billing rules permit it.
Consider a patient who visits a hospital emergency department.
The hospital may submit an institutional claim for eligible facility services. The emergency physician may separately bill for the physician’s evaluation and treatment through a professional claim, depending on the employment and billing arrangement.
The same principle may apply to hospital-based radiology or other diagnostic services. A facility may bill for its eligible technical component, while a qualified practitioner may bill for a separately payable professional component when permitted.
However, separate claims are not automatic in every situation. Some services may be bundled into a facility payment or subject to specific billing restrictions.
Remember: Institutional and professional claims are not simply two different ways to bill the same service. They represent different billing responsibilities, and the payer’s rules determine which services can be billed separately.
Why Is It Important to Understand the Difference?
Understanding institutional claims vs professional claims helps healthcare organizations maintain accurate billing processes and reduce avoidable claim issues.
1. It Helps Prevent Incorrect Claim Submission
Using the wrong claim format can lead to processing problems or rejection. Billing teams must determine whether a service belongs on an institutional or professional claim before submission.
A clear billing workflow helps staff identify the correct claim type and use the appropriate electronic format.
2. It Supports Accurate Coding
Institutional and professional claims may use overlapping code sets, but they do not necessarily use the same fields, reporting conventions, or billing requirements.
Institutional claims may require revenue codes and type-of-bill information, while professional claims commonly rely on procedure codes, modifiers, units, and provider-specific details.
Accurate coding begins with understanding the service being billed and the requirements that apply to that claim.
3. It Can Reduce Claim Denials and Rework
Missing information, inaccurate coding, eligibility issues, authorization problems, and payer-specific errors can delay payment.
For example, a professional claim may encounter a problem because a required modifier is missing. An institutional claim may require correction because of an incorrect type of bill or incomplete facility information.
Identifying these issues before submission can reduce avoidable rework. It cannot eliminate every denial, because some denials result from coverage restrictions, medical necessity reviews, or other payer decisions.
4. It Improves Revenue Cycle Visibility
When claim types are correctly categorized, billing managers can better analyze claim acceptance, denial reasons, reimbursement delays, and outstanding accounts receivable.
This makes it easier to identify whether a recurring problem is associated with institutional billing, professional billing, a specific payer, or a particular service line.
Better visibility also supports more informed decisions about staffing, training, automation, and process improvement.
5. It Helps Billing Teams Work More Efficiently
Billing staff often manage large volumes of claims across multiple payers and service lines.
Clear procedures for claim classification, coding, documentation review, submission, and follow-up help reduce confusion and unnecessary handoffs.
When the right information is available at the right stage, teams can spend less time correcting preventable errors and more time resolving complex billing issues.
Common Reasons Institutional and Professional Claims Are Rejected or Denied
Even when the correct claim format is selected, errors can still occur. Understanding common billing problems helps teams identify where improvements are needed.
Incorrect patient or insurance information: A misspelled name, incorrect member ID, or outdated insurance information can interfere with claim processing.
Missing or inaccurate codes: Diagnosis, procedure, revenue, or other required codes may be missing, invalid, or inconsistent with the service reported.
Provider information errors: An incorrect NPI, billing provider detail, rendering provider detail, or enrollment mismatch can create processing issues.
Authorization problems: Certain services require prior authorization or other payer approval. Missing or invalid authorization information can affect payment.
Incomplete documentation: The medical record may not sufficiently support the service billed or the applicable medical necessity requirements.
Duplicate claims: Submitting the same claim more than once without following the payer’s correction or replacement procedures can cause additional problems.
Timely filing issues: Claims submitted outside the applicable filing deadline may be denied unless an exception applies.
Payer-specific billing errors: Different insurers may have different requirements for modifiers, coding, documentation, claim frequency, and submission procedures.
It is also important to distinguish a rejected claim from a denied claim. A rejection generally means the claim did not pass an initial submission or data quality requirement and must be corrected before it can proceed. A denial generally means the payer has processed the claim and determined that payment is not due, in whole or in part, under its rules.
The exact terminology and workflow can vary by payer and system.
How to Improve Institutional and Professional Claims Management?
Improving claims performance does not always require a complete change to your billing system. Often, better processes and consistent reviews can make a meaningful difference.
Verify Patient Eligibility Before Billing
Confirm the patient’s insurance information and eligibility for the relevant date of service. Check applicable coverage limitations, referral requirements, and authorization rules.
Eligibility verification does not guarantee payment, but it can help identify potential issues before claim submission.
Use the Correct Claim Format
Establish clear procedures for determining whether a service should be billed through an 837I institutional claim or an 837P professional claim.
If paper claims are permitted, use the applicable CMS-1450 or CMS-1500 form and follow the payer’s instructions.
Review Claims Before Submission
Implement a pre-submission review process to identify missing fields, coding inconsistencies, provider information errors, and other correctable issues.
Automated claim edits can support this process, but they should be configured appropriately and reviewed regularly.
Monitor Rejections, Denials, and Payment Delays
Track the reasons claims are rejected or denied. Group the results by payer, claim type, service line, and error category.
For example, if your professional claims frequently encounter modifier-related issues, targeted staff training may be more effective than retraining the entire billing team.
If institutional claims repeatedly fail because of incomplete billing information, reviewing the facility’s documentation and charge-capture workflow may be the better starting point.
Train Staff on Payer Requirements
Billing rules can vary across Medicare, Medicaid, commercial insurers, and individual managed care plans.
Regular training helps billing teams stay familiar with applicable coding updates, payer policies, documentation requirements, and claim correction procedures.
Evaluate Your Revenue Cycle Workflow
Look at the full process, from patient registration and documentation to coding, claim submission, payment posting, denial management, and accounts receivable follow-up.
This broader view can help identify where delays originate and which improvements are likely to make the biggest difference.
How Medical Billing Support Can Help Healthcare Organizations?
Managing institutional and professional claims requires attention to detail, consistent processes, and timely follow-up. For hospitals, medical practices, and healthcare organizations handling high claim volumes, administrative pressure can build quickly.
When billing teams spend too much time correcting claims, reviewing missing information, or following up on unresolved accounts, other revenue cycle responsibilities may fall behind.
A structured medical billing workflow can support:
- More consistent claim preparation and submission.
- Timely identification of missing or inaccurate information.
- Better tracking of rejections, denials, and outstanding claims.
- More organized documentation and billing follow-up.
- Improved visibility into recurring process issues.
- More efficient use of internal billing resources.
The right approach depends on your organization’s size, specialties, payer mix, claim volume, and existing systems. Some organizations benefit from additional billing capacity, while others may need better workflow design, focused denial analysis, or stronger quality checks.
At GoSourceMD, healthcare organizations can explore medical billing and revenue cycle support aligned with their operational needs. The goal is to make billing processes more organized, reduce avoidable administrative friction, and support more consistent claims management.
Final Thoughts
Understanding institutional claims vs professional claims is an important part of managing medical billing accurately and efficiently.
Institutional claims generally represent eligible facility services and use the 837I or CMS-1450 (UB-04) format. Professional claims generally represent eligible practitioner services and use the 837P or CMS-1500 format.
The distinction goes beyond choosing a form. It affects the information reported, the billing workflow, the edits applied to a claim, and the way billing teams investigate processing problems.
For healthcare providers and revenue cycle managers, a consistent approach to claim classification, coding accuracy, documentation, and follow-up can help reduce avoidable rework and improve visibility into billing performance.
If your organization is reviewing its medical billing workflow, start by identifying where claim errors occur most often, which payer requirements create the greatest challenges, and where additional process support could make a difference.

Frequently Asked Questions: Institutional Claims vs Professional Claims
1. What is the difference between institutional claims and professional claims?
Institutional claims are used by eligible healthcare facilities to bill for facility services, while professional claims are used by physicians and other eligible practitioners to bill for their professional services. Institutional claims use the 837I format or UB-04 form, whereas professional claims use the 837P format or CMS-1500 form.
2. What is the difference between 837I and 837P claims?
The 837I is the electronic format for institutional healthcare claims, such as eligible hospital facility services. The 837P is used for professional claims submitted by physicians and other eligible practitioners. Using the correct format helps ensure claims meet the applicable payer submission requirements.
3. Is UB-04 the same as CMS-1500?
No. UB-04, also known as CMS-1450, is the standard paper claim form for institutional billing. CMS-1500 is the standard paper claim form for professional billing. Both are used when paper claim submission is permitted under applicable payer requirements.
4. Can a hospital submit both institutional and professional claims for the same patient?
Yes. A hospital encounter may generate an institutional claim for eligible facility services and a separate professional claim for a physician’s eligible services. For example, a hospital may bill for emergency department facility services while an emergency physician bills separately for professional evaluation and treatment, depending on the billing arrangement and payer rules.
5. Do institutional claims and professional claims use the same diagnosis codes?
Both claim types may use ICD-10-CM diagnosis codes, depending on the service and applicable requirements. However, their reporting rules and other claim details can differ. Diagnosis and procedure information must accurately reflect the medical record and follow the applicable payer guidelines.
6. What are the common reasons institutional and professional claims are rejected or denied?
Common issues include incorrect patient or insurance information, coding errors, missing modifiers, incomplete documentation, provider enrollment problems, authorization issues, duplicate submissions, and missed filing deadlines. Reviewing claims before submission and analyzing payer responses can help billing teams identify recurring problems.
7. How can healthcare providers reduce institutional and professional claim denials?
